Appncation Iiie october z3, 1902.

To all will/0m t may concern:

Be it known that I, WILLIS-S. JONES, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented ce'rtain'new and useful Improvements in Tie-Plates for Railways; and I do hereby declare that the following is a full, clear, and exact descriptionv of the same, reference being had to the accompanying drawings, and to the letters of of this specification.

This invention relates to tie-plates for railways of that class in which one or more longitudinal flanges are provided on the under side of the plate which engage the grain of the tie and act to compress the same beneath the plate and to more firmly hold the plate in position. Millions of tie-plates of various kinds are used annually in this country, the object of such plates being to afford a positive bearing-surface for the rail and to prevent brooming or cutting of the tie, due to the impact of the rails thereon during the passage of trains. Heretofore such plates have been made much heavier than has been necessary, or if attempts have been made to lighten the plates the result has usually been to materially decrease the strength of the same. This, While affording a profit to the manufacturer, seriously endangers the eiiciency and safety of the construction.

The object of this invention is to provide a tie-plate of such constructionas to affordl maximum strength with minimum weight, at the same time aiording improved Vmeans auX- iliary to the usual spikes for gripping the plate to the tie.

Theinvention consists in the matters hereinafter described, and more fully pointed out and defined in the appended claims.

In the drawings, Figure 1 is a perspective view of a transverse section of a device embodying my invention. Fig. 2 is a perspective view of the plate, showing the same inverted. Fig. 3 is a fragmentary longitudinal section of the same. Fig. 4 is a fragmentary transverse section thereof.

As shown in said drawings, the body of the plate comprises a broad bar of metal, preferseriai No. 123,406. (No moel.)

Aably rolled andl providing a comparatively broad plate and having alternately-arranged upper and lower longitudinal fiat bearing-surfaces A A A2 and B B B2 B3, respectively, forming a plurality of wave-like corrugations, which alternately afford a bearing upon the tie and a bearing for the rail-base, with intermediate grooves or channels between the bearings on each side of the plate, as shown.

Each of the lateral margins of the plate are turned downwardly, as shown in Figs. l and 4, providing lateral side flanges cc, the surface of which from the lower edge curve inwardly to meet the plane of the under surface of the ribs or bearing-surfaces B3. At the longitudinal center of the plate and located below the bearing A a comparatively broad sharp iiange C is provided, which serves to engage in the wood of the tie beneath the middle of the plate, compressing the same laterally and positively engaging the plate with the tie. As shown, a comparatively narrow longitudinal iiange is provided on the under side 'of the plate, at or near each of the bendsof the same and indicated, respectively, by c, c2, and c3. Said flanges 0,0', c2, and@3 are all approximately of the same width, as shown in Fig. 4, and serve to positively compact between the same the wood or other material of the tie, affording a vbetter bearing-surface for the plate thereon and aiding in aifording positive engagement with the tie. One or more of said flanges are of less length than the length of the plate, which projects-beyond the ends of the same at each end suiiiciently to afford a comparatively broad lower bearing-surface at each end of the plate.

Each of the concave channels in the under side of the plate are closed at the ends and beyond the ends of the longitudinal flanges by the downwardly-turned sharp claws D d, of which the claw D is opposite or adjacent to the ends of the iange C, closing the central channel on each side of said flange and between the iianges c c. rlhe flanges cl are located adjacent to the ends of and between the flanges c2 c3, closing the ends ofthe channel Vbetween downwardly-turned transverse claws on the IOO under side of the plate, (indicated by Z,) which are similar to thc claws D and CZ and extend below the plane of the under surface of the plate and engage the tie transversely of the grain. Said .flanges D Z d are provided with sharp chisel-shaped edges extending transversely of the grain of the tie, and the faces of the same are directed against the greatest thrust on the plate, or, in other words, toward the outer end of the same and are at and approximately perpendicular with the plane of the plate. Spike-holes in any desired number are provided through the plate, preferably passing through the upwardly-turned ribs, bearings, or bars A and A2, as shown in Figs. l and 2 and 4.

The operation is as follows: The tie-plate is bedded upon the tie, with the claws of transverse flanges D d directed toward the adjacent ends of the tie, or, in other words, toward the outer side of the rail to be supported thereon and all of the flanges positively engaged in the tie. Any slight crack or seam formed in the tie at the ends of the longitudinal flanges is positively closed by the transverse flanges D d and the overlapping ends of the tie-plate, so that dirt or moisture cannot find its way therein` Owing to the bends or corrugations in the plate much less thickness and weight of metal need be employed to obtain a required strength, as the longitudinal flanges serve to greatly strengthen the plate at the bends, forming, in effect, at each bend a longitudinal truss. lt is also obvious that each of the transverse flanges D d d serve as a transverse brace or truss across the grooves or channels in the under side of the plate, the metal being displaced downwardly in punching while remaining integrally connected with the metal on each side of the same. The plate owing to said transverse flanges is rendered practically as strong. transversely though very much lighter than plates constructed as heretofore.

Obviously the plates may be made of any desired width, and the number, size, and disposition of flanges may be varied to suit varying conditions, and many details of construction may be varied without departing from the principles of this invention.

I claim as my inventionl. A plate of approximately uniform thick- 'ness waved or corrugated transversely to provide a plurality of lower flat bearing-surfaces for engagement on the tie and upper flat bearing-surfaces arranged alternately therewith to support the rail, and one or more longitudinal flanges on the under side of the plate of a length less than the lengthof the plate.
